Hi,
I used the VideoLan client (www.videolan.org) instead of MPlayer.
I found it much more rich featured. It can turn unicast stream into

almost any known OS.

I haven't tried this myself, but if it does support the Windows Media 9
Audio codec, go for it. Currently MPlayer does _NOT_ support this codec,
which is closing out any unix/linux/*bsd users from hearing the sessions
as our encoding only supports Windows Media 9 audio codecs.
The obvious solution is that we change our encoder to use the previous
codec (as used in Barcelona in May). Unfortunately, MS is not making the
Windows Media 8 Audio codec available for their encoder (they do for the
player) anymore. I'm somewhat redfaced that I didn't keep the original
install file before having the machines reinstalled at the moment.

Subject: [ripecast] mplayer doesn't know the audio codec used (0xA)
Message-ID: <20030903014845.GA69349@xs4all.nl>
Hello RIPE Webcast people,
I've tried to view the sessions being webcasted, and a problem.
The audio codec used is not supported by mplayer, and I haven't been
able to locate any other open source program capable of playing these
streams.
Mplayers identified the audio stream as follows :
======= WAVE Format =======
Format Tag: 10 (0xA)
Channels: 1
Samplerate: 8000
avg byte/sec: 1000
Block align: 300
bits/sample: 16
[..]
Cannot find codec for audio format 0xA
A fairly extensive google search for the problem finds a few people who
have the same problem, but no solutions.
Checking the mplayer sources ( mplayer-1.0pre1 , latest release) shows that
this codec/format is indeed unknown.
I'd appreciate it if you could change the codec to either plain PCM, or
MP3, for example.
(Actually, what -is- the codec used at the moment ? )
Unless I missed something perhaps, in which case I hope you can provide a few
pointers on how to use mplayer (or any other free unix tool ) to view and
listen to the webcasts.
-----
Apart from this problem though, I'd hope that RIPE would use non-propietary
formats in general as much as possible.

I'm trying to view the transmission using MPlayer. The video is working
as expected, but I cannot decode the audio stream:
Cannot find codec for audio format 0xA.
Do you have any idea how to get the audio with MPlayer? I'm using Debian
Woody with the stable mplayer-686 and the full w32codecs packages from
Marillat.
TIA,
Andre.

Is there any way you can recode the streams? I'd really like to see some of
the sessions, and I cannot use windows.

Message-ID:
Dear Colleagues,
As many of you have noticed, we currently have a problem where the audio
we are encoding into, cannot be heard under (generally) linux based
players, as no codec exists.
Unfortunately at this present time we have been unable to find a solution
to this, and we apologise unreservedly for something we should have
foreseen.
We will keep trying to find a solution (pointers/suggestions welcome!)
during this week and after RIPE46 has finished, we will redouble our
efforts to find such a solution.
Once we find a solution, we will re-encode the archives that are being
made of our sessions.
Again, apologies for you not being able to hear the audio at this time and
thanks for your interest!

This problem has now been fixed. I've managed to get the older Windows
Media Audio 8 codec installed on our equipment (an epic in itself), also
using the same video codec (7) as before.
If you wish to test it overnight before the main sessions resume in the
morning, I've left the audio-only feed running at:

Currently (01:42 CET/Amsterdam time) there are no broadcasts thus
one can't watch them either. The archives (bottom of the page)
work, at least the IPv6-wg one did with Windows Mediaplayer 9 over
my home DSL line. I haven't tested the live feeds but I understood
from Jakub Vlasek (.cz) that he had quite a clear live feed there...
BTW I wonder if the RIPE webmaster could either: directly store
a ripe meetings url as:
http://www.ripe.net/ripe/meetings/ripe-46/webcast.html
or directly as:
http://www.ripe.net/ripe/meetings/archive/ripe-46/webcast.html
BTW I wonder what the idea is of moving it to archive after next
week or somewhere as it is pretty clear that the current one
is the last one etc. also a simple redirect under eg
/ripe/meetings/current/ and /ripe/meetings/previous/ could
help out there saving us from retyping this message then as
all of the 'current' url's get invalidated in the mailarchives.
Which is something quite unfortunate. Note that there is a w3c
tip about this on their site.
Greets,

Just FYI, right now (4.9., 11:35) my WMP (V9) on XP refuses to play any

This is the Audio format issue that we've previously been mentioning. The
live stream, and archives created today, are using the Windows Media 8
audio codec, which MPlayer supports.
You would have gotten this problem on sessions recorded prior to today,
when we were using the Windows Media 9 audio codec, which MPlayer doesn't
support and complains of unrecognised '0xA' format.
Kind regards,

Hi there,
A few small comments on the video stream:
- First, thanks for offering it!
- mms://stream-ripe.wind.surfnet.nl/ripemtg works a lot better than
mms://webcast.ripe.net/ripemtg from where I'm sitting (AMS-IX offices,
AS1200)
- Are you considering multicast?
- You may want to add VLC (VideoLanClient) http://videolan.org/ to the
list of working media players; the Mac OS X version is especially nice.

This could be that the webcast.ripe.net server is having trouble with too
many connections (The mirrors are also grabbing their feed from there).
I haven't really looked at this machine during the meeting.

Not a problem for this.

Message-ID: <17852.1062758013@www64.gmx.net>
Hi,
there seems to be a problem with the archived webcast of NCC Services 2
(Thursday Morning 11-12.30). While other sessions are accessible without problems
this one is not:
mms://webcast.ripe.net/ripe46/services-2.wmv
Thank you very much for checking and the offering of the webcasts in
general,
Monika
PS. Live Webcast varied much in quality, sometimes connecting from my place,
T-DSL line in Southern Germany, was nearly impossible, because of regular
new buffering. Audiocast was completely unavailable yesterday evening and this
morning (because of "to many sessions").

Message-ID: <20030905152057.GA64679@xs4all.nl>
Hello Bruce & other ripecast people,
Thanks for finding a codec that works on Linux for thursday and later.
(actually, I think it was already on wednesday or perhaps thursday morning
that the audio-only session already worked, while the video session didn't.
Was that your trial setup of the other codec, or a different setup from the
start ? )
I'd appreciate it if you could update the archive website to include
information on which codec was used for which session.
It would save futile downloading of earlier sessions made with the
non-supported codec.
Also, any idea when you'll be able to re-encode the earlier sessions, as
mentioned in Mally McLane's mail to the list ?
Thanks, regards, Boudewijn Visser

I guess you may want to fix it.

Mistype on my part; its been corrected.

We used the RealNetworks video format for the January meeting (RIPE44),
and weren't too impressed with the video quality and certain other issues.
Whilst we won't be using Real as the source encoding again, we _may_ (for
RIPE47) re-encode the stream on the fly to Real (and possibly QuickTime)
as an option.

During the meeting, both streams originated from the same machine, and
were using the same codecs.

This change has been made. I also hope to get the sessions re-encoded on
Monday.

Well, there must be a few tweaks to the settings, since for example the
eix1.wma audio only session of wednesday plays fine on mplayer.
So apparantly the new software you used does still have the capability
to encode audio in other formats.
(mplayer output for eix1.wma audio session)
============ ASF Stream group == START ===
object size = 32
stream count=[0x1][1]
stream id=[0x1][1]
max bitrate=[0x4f8a][20362]
============ ASF Stream group == END ===
Clip info:
name: RIPE46 Audio Stream
==========================================================================
Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders
AUDIO: 22050 Hz, 2 ch, 16 bit (0x10), ratio: 2501->88200 (20.0 kbit)
Selected audio codec: [ffwmav2] afm:ffmpeg (DivX audio v2 (ffmpeg))
==========================================================================
(checking...)
Same for the routing-1 audio only session of tuesday.
mms://webcast.ripe.net/ripe46/routing-1.wma
...
routing-2.wma is OK too. [apart from a terrible noise some 40 seconds from
the start, like someone is using a high-pressure cleaner nearby].
dn-3.wma OK.
So at least for audio-only sessions your original software could encode
in a supported format.
If you can find the right settings to make it do that for video+audio too
it might save you the trouble of digging up the old software next time ;-)
I didn't try them all, but it seems safe to say that all audio-only
recordings work with mplayer, and only the combined audio/video sessions
before thursday have the audio problem.

Subject: [ripecast] webcast codecs
Message-ID:
Thanks for the web cast - I didn't use it much - but did get my Linux
box to display it with the old codecs - well done!
The fun and games with the codecs for the live broadcast made me think
about the format for the archives.
The problem of data formats and long term archive is well known. Data
has been lost due to lack of equipment to read the media. The problem
with lack of code or specification to parse data probably hasn't hit
yet but is becoming more likely with more and more proprietary
standards that need a specific piece of code to read it.
RIPE meeting archives are likely to be around for a long time. To make
sure future generations can still view them I suggest the webcast
archives are encoded in a well know publicly specified codec like MPEG
rather than a transitory proprietary standard like the ones we had
problems to support even today.
I suspect that I will be able to find an MPEG decoder in 10 years time
more easily than one for the codecs that were used for live broadcast.
Using the latest codec-du-jour for the live broadcast is not a
problem, the important point there is to get as much quality for your
bits in a codec that is available on the current popular platforms,
it's just the long term archives that need to be in an open standard.
Chris.
PS I've confused the various terms open, closed and proprietary
etc. The important points for archiving are that they are well known,
widely implemented and well documented so that in 10 years we can find
or build an application that understands them.

Some of the sessions were still on the meeting server when the meeting
network was pulled down. I've now copied them across, so that the above
and the Friday plenary sessions are now viewable.

I'm not sure I understand what you mean here.

The too many sessions problem is with our machine (webcast.ripe.net) as I
had it configured to give priority to the mirror feeds. This needs to be
looked at before the next meeting.

The machine 'webcast-rm.ripe.net' was setup for our RealMedia test for
RIPE 44 in January. Since then, the machine has been turned off, and we
are not relaying the webcasts through this machine.
RIPE45 and RIPE46 utilised Windows Media for the webcast, and the public
access machine of 'webcast.ripe.net' is still up and running (check
http://www.ripe.net/ripe/meetings/ripe-46/webcast-archive.html for archive
links )

Hi Bruce,
I just checked, but it seems none of the monday-wednesday sessions have been
re-encoded yet with a codec that mplayer supports.
Any idea when you'll be able to do that ?

Some of them have been re-encoded, but I haven't been updating the web
page to link to the new files. I've fixed this (sessions with
yellow backgrounds haven't been re-encoded yet) and will keep it updated.
( The re-encoding is being done by playing back the session files, so
there is some loss of video and audio quality. The original files are
still in place however. )
